## What Are Modules Imagine [[Terraform modules]] as pre-built [[Infrastructure As Code]] templates. They're like recipes for your favorite meal, containing everything you need to serve up a functional infrastructure environment. Using modules, you avoid the tedium of starting from scratch each time you need to create infrastructure. Instead, you tap into a well-organized library of pre-configured elements, streamlining the setup for yourself and your team. Why is this modular approach recommended for nearly any Terraform setup? For one, it abstracts much of the complexity involved. Think of it as a layer of simplification, enabling end users to consume complex configurations without delving into every intricate detail underneath. This allows teams to focus on what they do best, delegating the heavy lifting of infrastructure management to consistent, reusable components. Modules make Terraform not just a tool, but a platform for shared growth. By encapsulating your configurations, you build an environment that's easier to manage and extend. This fosters a collaborative ecosystem where teams can adapt and reuse modules across different projects and organizations. The cycle of 'build, reuse, refine' becomes a natural workflow. ## Benefits of Using Modules A tangible benefit of modules is their role in promoting self-service within organizations. By providing a catalog of modules tailored to common use cases, infrastructure becomes more accessible. Teams no longer need to reinvent the wheel; they can deploy complex configurations quickly and consistently. Terraform modules aren't simply about efficiency—they're about empowering developers and IT teams to achieve more with less friction. In a field where time is scarce and demands are high, modules represent a key strategy to navigate and thrive.
